    Importance of Shifter in E-bike

    I am planning to build a new e-bike for myself. I want to ask how important is the parts like shifter, derailleur and freewheel.

    Will they affect the speed. As i live in a hilly area i don't want to have trouble while climbing. And if they are important which part is more important. Sorry for my newbie question

    I think most of you are pretty familiar with it but i want to mention. I will not use pedal assist as i am in USA. I will use throttle .

    I don't want to spend a great money for some upscale shimano products. Appreciate all answer

    I really don't understand why one would not want pedal assist and a throttle... More choice usually always ends up being better in the long run for overall riding pleasure. JMO I pedal my bike all the time without the pedal assist on/with the pedal assist on/with the throttle..

    As for your questions, pedaling effects everything, speed, distance per charge, normal riding experience, the battery usually ends up being most important part, so don't skimp on that...

    Depends on the drive system. If you're using a hub motor (either direct drive or geared), the bike's gearing will have no effect at all on the motor output. You could go single-speed with a chain tensioner and not even have shifters or derailleurs and it would only affect any pedaling you do.

    If you're using a mid-drive, the motor drives through the bike's rear gearing so having a good rear derailleur and shifters is important. If the bike you're building on has indexed shifting and shifts easily and cleanly through all the gears now, then you probably don't need to change anything. But if the shifting is "iffy" now, then putting a bunch of power through it will likely make any existing problems worse. You don't need to have a high-end drive train, but you do need to have something that's functional. A low-end Shimano group (like Tourney) is every bit as capable of handling a motor as the fancy stuff if it's installed and tuned correctly.

    Thanks for the answers. Yeah i forgot to mention that i will use a hub motor. There will be Pedal assist but i think i will rarely use it.

    SO i am just trying to optimize my limited budget.

    Pedal assist will give you a far greater range.. Throttle is great for whipping around locally, picking up milk & bread at the grocery store.. but if i'm going over 20km distance, it's pedal assist all the way so i don't get the dreaded 'battery meter' anxiety.. 30km or greater then i'm going to be looking for juice up points...I'm hoping in a year or two they'll have 100km+ batteries..or faster recharge rates..until then pedal assist in a must if you really want to use it for distance.

    Hub motors dont have much torque for climbing steep hills , but will boost speed ..

    a mid drive applying power to the whole drivetrain will let you use the mechanical leverage of the low gears in the drive train..
